- Version 5 only runs on Leopard, Snow Leopard and Lion (OS X 10.5 or higher).
- Version 5 is Intel only; PowerPC Macs are no longer supported.
-
- Mobile companion app for iOS suport called Pocketpedia.
-
- 10 point rating system with half stars (click on a star again to change to half star).
- New dedicated media server for the Pedias, Doghouse, with support for all languages and countries. Doghouse is built from Pedia users uploading and sharing their data with other Pedia users so the more you share, the better it gets!
- Added 4 new fields, specifically for TV: Season, Episode, Creator and Series.
- Added 8 new custom fields: two date fields, two checkboxes, two tag fields (aka multi- value, blue bubble fields) and two regular text fields.
- Custom field names can now be changed in the Preferences > Fields tab, removing clutter from Preferences > General. Just double- click the custom field name in the "Fields" list and enter your new title. Mousing over a custom field title in the list will reveal the original custom field name.
- New details view styles.
- A new generic detail view template tag that is automatically expanded to include all fields selected in the Preferences > Fields, making the creation of detail templates easier: [key:genericField].
- Optimized secondary search options (the 'limit to', 'search for', 'sort by' drop down menus) now show only those available for the selected search site.
- Results for advanced info found via the gear button in the edit window can now be browsed and previewed before adding the correct one.
- Enter a barcode into any active text field simply by scanning it with a Bluetooth or OPN scanner. Outside of a text field, scan a barcode for quickly finding an entry in your database (no need to go into the search field first).
- Plug- ins can now have their own preferences accessed through the little gear button in Preferences > Sites. These are accessed through the little gear button next to a site in Preferences > Sites.
- Default loan period (found in the Preferences > Fields) can now be 0 if no set period is desired.
- New 'Open URL' toolbar button to visit the entry's associated webpage.
- New settings for date format based on international standards.
- New smart collection criteria: "Cover Image is/is not set", to easily group items without covers.
- Some fields including genre, tags and director, are now clickable in the details view to filter the current collection by that attribute. Similar to doing an internal search but a lot quicker.
